A balanced diet provides the right types and amounts of foods and drinks to maintain health. It includes major nutrients like proteins, carbohydrates, fats, vitamins, and minerals. Proteins help build muscle and boost immunity. Carbohydrates provide energy while fats transport vitamins and insulate organs. Vitamins and minerals support various bodily functions. A balanced diet along with physical activity and supplements can help ensure adequate nutrient intake and prevent deficiencies that impact health. Maintaining a positive attitude also contributes to overall well-being.

Nutrients are components of food that are needed for the body to function
Life cannot be sustained without adequate nourishment.
Man needs adequate food for growth and development and to lead an active and healthy life.
Food plays an important role in maintaining a person's nutritional and health status.
PLANTS
Many plant & plant part are eaten as a food.
Seeds are good source of food for animals including humans because they contain nutrients.
All seeds are not healthy. Eg- apple seeds & cherry seeds contains cyanide.
Food can be defined as anything edible that can be solid, semisolid or liquid which when swallowed, digested and assimilated in the body, proves useful to it. These substances not only keep the person alive, but also provide energy used for growth and development, regulate the body processes and protect the body from diseases.

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

2. WHAT IS BALANCED DIET???
A balanced diet means getting the right types and
amounts of foods and drinks to supply nutrition and
energy for maintaining body cells, tissues, and
organs, and for supporting normal growth and
development.
5. NUTRIENTS
2 types of nutirents-
1. Major- protein,carbohydrate,fats
2. Micro- minerals-
calcium,magnesium,phosphorus,zinc,selenium
Vitamins- a,d,e,k,c,b group
Water
6. PROTEINS
1. Helps in tissue and muscle building
2. Boost up immunity
3. Helps to maintain fluid balance
4. Healing
Deficiency- muscle wasting, weight gain, poor
immunity and low hb.
Sources- milk and milk products, soya
bean,beans,dals,egg,chicken,fish.
7. CARBOHYDRATES
1. Energy giving compound necessary for daily activity
2. Necessary for proper working of brain,heart,nervous
tissue.
2 types of carbohydrate
A. Simple- refined flour, glucose
B complex- fibers
Role of fiber: helps in weight reduction, proper bowel
movement and healthy intestine
Sources: wheat,oats,brans,vegetables,whole cereals
and pulses, fruits.
8. WHAT HAPPENS IF IT IS IN EXCESS OR
LOW??
Excess- weight gain,diabetes mellitus,insulin
resistance,hypertriglyceredemia,CAD
Deiciency- constipation,low mental
performance,ketoacidosis.
9. FATS
The main function is to give energy
Important for transport of vitamins a,d,e,k
Covers organs acts as insulators to our vital organs like
heart,kidney,liver.
Types of fats: saturated and unsaturated.
Saturated- solid at room temperature ghee,butter,coconut oil.. This is
bad for our health..
Unsaturated-liquid at room temperature, omega 3 fatty acid omega 6
fatty acid… good for our health
Sources: olive oil,rice bran oil, soyabean oil,groundnut oil,mustard oil
Good source of omega 3 fatty acid- almonds,fish,walnuts.
Deficency- vitamin deficiency,dry skin,nervous disorders
Excess- weight gain,elevated blood lipid levels,CAD
10. RDA FOR MAJOR NURTRIENTS
Carbohyrates- 65% of total diet
Proteins- 1g/kg of body weight
Fats – 3-4 tsp oil and 1 tsp ghee..aprrox 0.5-1
L/person in a family.
11. WHAT IF OUR DAILY DIET LACK ALL THESE
NUTRIENTS???
It leads to a condition called Protein energy
malnutrition simply called as malnutrition.
In Madhya Pradesh alone, about 53% children are
malnourished it include upper middle class children
also..
Cases of cancers has increased two fold.
Reason??? Lack of fiber in diet
So what's the remedy???? Inclusion of Protein
supplements in our diet. Inclusion of high fiber
supplements and food in diet.
12. MINERALS:
Inorganic elements found in food that are essential
to life processes
About 25 are essential
Classified as major or trace minerals
RDA’s have only been determined for 7 minerals-
calcium,phosphorus,sodium,pottasium,magnesium,i
ron,zinc
13. CALCIUM
Helps in proper bone formation
Cells signalling,blood clot formation,muscle
contraction.
Sources – dairy products,
Green leafy vegetables, beans,
Fish.
Lack of calcium in diet leads to
Osteoporesis,frequent fractures,
Muscle cramps, obesity.
Rda- 1-2 g/d
14. IRON AND FOLIC ACID
Most important for proper haemoglobin levels in our
body.
Its deficiency causes anemia..
Sources of iron : red meat,
Egg yolk,beans and legumes,
Dried fruits,fruits,ragi,bajra,
Jowar,jagrey, sprouted and
Fermented food products
Rda for iron: 30mg
15. SODIUM
A mineral that regulates body fluid volume,
concentration and acid-base
sources: table salt (sodium chloride), foods
processed with table salt, milk, milk products,
eggs and seafoods
16. OTHERS
• Magnesium: A mineral found mainly inside muscles, soft
tissues and bone. It functions in many enzyme processes.
• Zinc: A mineral involved in wound healing, taste sensation,
growth and sexual maturation and part of many enzymes
regulating metabolism
sources: meat, liver, eggs and seafood (oysters).
• Iodine: Iodine is needed for the normal metabolism of cells.
Metabolism is the process of converting food into energy.
Humans need iodine for normal thyroid function, and for the
production of thyroid hormones.
Sources -Iodized salt is table salt with iodine added. It is the
main food source of iodine.Seafood is naturally rich in iodine.
Cod, sea bass, haddock, and perch are good sources.
Deficiency – Hypothyroidism
17. VITAMINS
Are complex organic substances
Normal growth, maintenance, and reproduction
Your body cannot produce all vitamins you can
get those by eating a nutritious diet.
Fat-soluble vitamins: carried in fatty parts of
foods and dissolve in fats (body stores them
in fat... build up can be dangerous)
Water-soluble vitamins: dissolve in water
(body does not store them)
18. FAT SOLUBLE VITAMINS
This group of vitamins
need fat for their
absorption.
Deficiency of vit d lead to
bone disorders
Deficiency of vit a leads
to night blindness,poor
eyesight,skin problems
Deficency of vit e leads to
skin disease and
problems
Vit k deficiency leads to
poor blood clotting..
19. WATER SOLUBLE
Vit c defiency leads to scurvy,poor wound
healing,anemia,heart problems
20. DEFICIENCY AND SUPPLEMENTS
The normal rda for mineral and vitamins are
Calcium-1-2g/d
Iron-28-30mg.d
Vit A-2400-3000 I U/d
Vit E-10-15 mg.d
Vit D-400-500 I U / d
Vit K-50-80ug/d
Vit C-40mg/d
B12-3-2mcg/d
Sodium-2-3g/d
21. WHAT IF ALL THESE NUTRIENT ARE LACKING IN
OUR DIET???
Although all the mentioned vitamins are present in
our daily diet but some how or the other their
absorption is not proper.
Reason??????
Lack of vit c might leads to poor absorption of iron.
Lack of vit d leads to calcium deficiecy.
Heavy bleeding during mestrual cylcle leads to
anemia
So one cannot depend completely upoon the food
to meet RDA
Here supplement play important role.
It provides all the necessary amount of nutrients to
our body.
22. DIETARY SUPPLEMENTS -BENEFITS
Enhance immune system
Antioxidants
Reduce risk of CAD, stroke
Decrease risk of Cancers
Decrease risk of Cataracts,Arthrits,Macular
degeneration,Alzeimers
Improvements other chronic diseases
23. WATER
Water is your body's most important nutrient, is
involved in every bodily function, and makes up 70-
75% of your total body weight. Water helps you to
maintain body temperature, metabolize body fat,
aids in digestion, lubricates and cushions organs,
transports nutrients, and flushes toxins from your
body.
Daily minimum 10-12 glasses of water should be
taken..
24.
25. PHYSICAL EXERCISE
Daily 30-45 mins of physical exercise should be
done or 3-4 hrs per week..
Physical exercise can be of any type-
walking,jogging,swimming,aerobics,yoga,cycling.
26. TIPS FOR HEALTHY DIET
A well balanced diet including food from all nutrients
in correct form
Engage in regular physical exercise atleast 30 mins
Positive attitude
Keep smiling always.
